msnwasnmo uacn'mn Application filed Hatch 5,

This invention relates tqa dishwashing machine, and has for its object, broadly, to provide a machine for general household use whereby water may be applied to the dishes while confined in a rotating basket for efi'ec- 'tively removing grease or other adhering substances, the parts to be arranged. convenient for use and requiring very slight attention of an' operator. V

' One oft-he objects of the invention is to provide. operating parts which may be actuated by use of a limited degree of power, said parts operating for causing coincident rotation of a basket or dishholder and for moving or discharging water for cleaning and cleansing the dishes.

Still another object is to provide a machine consisting of few parts which may be conveniently assembled and may be manufactured at a limited expense and will perform all required functions for washing and cleansing in such a manner that the work may be speedily accomplished and that injury or breakage of the dishes-may be avoided. 2 The invention includes the use" of a tank .for supplying hot Water charged with soap or other detergent, and a second tank of hot cleansing water, and means for controlling the flow of these waters. Also the invention includes means to cause oscillating movements of the basket so that the dishes therein will be effectively cleaned by the water thrown against them,

With the foregoing objects in view and others to be mentioned the invention presents a new and useful construction, combination and arrangement of parts as described and pclaimed and as illustrated in the accompany-' ing drawgigs, it being understood that changes m y be made in form, size, proportion of parts and minor details, said changes being within the-scope of the inventionas claimed.

Inthe drawing, .Fig. 1 is a partlyb-roken away view in longitudinal section showing one embodiment 'of the invention. fFig. 2 is a perspective view of a rotatable frame.

Fig. 3 is a plan view of a track for the rotatable frame. Fig. 4 is a' diagrammatic "view for illustrating the trackshown in Fig.

erably being constructed of wire mesh, said basket being removably seated .in said holder.

at various angles to the direction of water -movements may be greater or less than men- 1928. Serial no. asao'za' 3, the circular track bein extended longitudinally to clearly show epressions and risers of the track. Fig. 5 is a detail showing the mounting of a vertical shaft upon a rotatable frame.

Referring now to the drawing for a more particular description numeral 1 indicates a support or frame upon whichis "mounted a cylindrical container 2.

Numeral 3 indicates a circular track which is mounted in the container 2 near the bottom thereof, said track being provided with depressions 4 and elevated. portions or risers 5. Numerals 6' indicate a pair of U-shaped bars or metallic strips disposed crosswise and secured together at their bases and providing a frame or holder 7 having wheels 8 for engaging the track.- Numeral 9 indicates a foraminous basket, its sides and bottom pref- Since the wheels 8 are disposed diametrically opposite to'each other it will be seen that when one wheel is disposed upon a riser or elevated part 5 of the track the other wheel 8 will be disposed in a depression 4 of said track, each riser being disposed diametrically opposite to a .de ression, the result in operation being that i the frame which carries the basket'is rotated, these parts will have swinging movements transversely of the container 2,-and according to the present construction shown, the frame and basket, during operation, would have six swinging movements during one complete'rotation of said frame.

. The advantages derived from the swinging movements mentioned is to permit the dishes or othercontents of the basket to be disposed on which may bethrown against them. While -I have shown that the frame and basket have six swinging movements, this feature may be changed, if desired, and the number of these i 5 tioned for each rotation of the frame 7 I provide a tank 10 for containing water charged withfwashing-powder or soap, and provide a tank 11 adapted to contain water for cleansingpurposes, said tanks being procommunicating with the rotary pump, said pipe 17 being in communication with the tank 10' subject to the control of a valve 18 and being in communication with the tank 11 subject to the control of a valve 19.

At 20 is indicated an upright conductingpipe which communicates with the pump 16, the upper end terminating adjacent to the top of the container 2.

- A lid 21 is provided for the cylindrical con tainer 2 and is hingeably mounted thereon as indicated at 22. Numeral 23 indicates a sprinkler which is carried by the lid 21, and at 24 is indicated a hose section in communication with the sprinkler and with the up right conducting-pipe 20.

As thus described it will be seen that if the pump is rotated watermay be moved from the tank 10 to be discharged into the container 2 and basket 9 from the sprinkler 23, the valves lt and 18 being open and the valves 15 and 19 being closed, and the water, of course, may be moved repeatedly through said tank-10 while the valves remain in the conditionmentioned, and this isthe operation for applying the waterto the dishes from the tank 10. The water in this tank thus charged withsoap or other detergent and heated by its burner 13 will be discharged from the sprinkler while the basket is rotating, and since the frame or holder 7 and basket 9 have the successive swinging movementsmentioned all adhesive substances will be removed from the. dishes, and any loose particles of food contained in the water during this operation will be caught by the strainer 12 and may be removed.

The operation for cleansing the dishes is practically the same as already described, the

valves 1.4 and 18 being closed and the valves 15 and 19 bein moved to-open position.

After the dis es have been cleansed, the

lid 21 may be swung to open position and the basket together with the dishes therein.

may be removed from the holder-frame 7. The tanks 10 and 11 are provided with faucets (not shown) so that the water may be conveniently removed therefrom whenever desired. I a

The parts shown herein for coincidently rotating the frame 7 and actuation of the tailed description. Numeral 26 indicates a mounted on t at end of the operating-shaft opposite to the rotary pump.

Any suitable coupling may be provlded for a connection of the vertical shaft 26 with the base of the frame 7 of the basket-holder which will permit said frame 7 to have the swinging movements mentloned transversely of the container 2, the coupling shown herem belng the flat tongue 33 which projects-downwardly from the base of the holder-frame 7 'at its 'middle part, said tongue being removably mounted between the terminal wings 34 of the vertical shaft 26, a bolt or pivot-pin 35 being used for connecting the wings with said tongue. I

The bottom of the container 2 is provided, centrally thereof, with a tubular bearingmember 36'for the vertical shaft, said tube being provided with packing 37 to prevent leakage of any water from the container.

In operation, water may flow freely through the container 2 subject to the control of the valves 14 and 15 and in operation,

basket in said frame, means-for rotating said frame, and means for said basket.

In testimony whereof, I have aifixed my signature.
